Stb all lwhom it may concern:

Alle it known that LGEonens C. CosMorien residing at Bucharest.,Roumanie, haye invented new and use-ful In'iprovements in tx'le--lloxesfor Railroad-Cars, of which ^the tollowing'g is a specification.

'lhis invention relates to an axle box for railroad ears and is intendedto enable always pure oil to be fed to the journal running' in the axlebox at each revolution andA elmmbers receiving' the dri i oil, whilebe-` tween the lid and the partitions of the bearin;1 box a lubricatingring which is secured aejainst axial displacement is mounted on thejournal. This ring takes the oil `From the eolleetiug chamber, which oilis scraped ntll the highest point of the lubricating ring by means of ascraper bearing strongly against the ring, and reconveyed to the upperoil ii-hamber.4

rtwo Vforms of construction ot' the object et the invention are shown inthe accompanying; dra wings, in which Figure l is a vertical; and Fig.2, a hori ',contal longitudinal ser-tion of the first form otromtruetion of the axle box; Fig. 3 shows sections on the lines Afm-lland C-D of Vig. 1: liigr. t is a vertical longitudinal seetiou ot! thesecond lorm ol2 construction; and itin. 3 bows cross sections of thelsame on the lines llt-lf and tlll ot Fig. 4;.

The bearing box l. which is made in one piecej is diiided in its lowerpart by partitions if, Il and l-. into chambers 5, t), 7 and 8. Thepartitions Il and =l are provided willi apertures l), l and '11 throughwhich i the oil muy be conveyed to the chambers 7 and A. lubricatingring l-l is mounted en the shoulder l2 ot the axle journal 15h whichlubricating ring is revolved by means ot catches on the axle, but it isnot displaceahle longitudinally to the axle. 'lhe lubrieating ringprojects into the chamber S and revolves between the cover 15 and theside walls .t6 and 17 ot the bearing,r box. whereby a lateral joint islorrned and simultaneously lateral movement is prevented. By the use `tthe ring any churning of the oil is also ayouled, The oil litted 'by thelubricating l yring 1-1- is removed hy lthe scraper 1l) and 'conveyedinto the chamber 21 `'mclosed by the bearing box and the bearing plateQ0. The scraper 19 is guided between ribs QQ Land pressed by a spiralspring Q3 onto the llubricatiug ring. rishoulder or tread 18 yprovidedon the lulu-matingring prevents the oil running otl" toward the cover15. Lubricating passages 211 lead to the journal from the chamber 21..

As will be observed from the drawing, the lubricating ringr tft titstightly between the side cover l5 of the axle box and the side Vall 16formingl a part ol. the cover of the ehatnber 8, so as to 'term with thesame a completely closed cover tor said chamber.

In order to prevent losses of the lubricant and penetration ol dust intotl i axle box, a packing or washer rinc,T and leather disks Qt and 27are arranged on the axle box so as to bear on the journal, as shown inFigs. 1 and 3. Dust particles which may i have reached the axle box overthe packingr lring,r ar anged between the axle and its journal` asshown, are prevented by thev leather disks 26 and 27llroin penetratingrliuto the oil chambers and are deposited in the chamber 5, from whichthey may be easily removed through an opening); 98. The axle box isfilled through the aperture QD (Fig. Il i The action ol the arrangementhereiubet'ore described is asitollows:--'l`he lubricating ring- 14 onthe rotation ot the axle lifts the oil trom the chamber tl upward intothe chaniber 2.1 from whence it is supplied to the journal:throughthelulu'ieatiuer passage-i 24. The oil again dripping otl' the journalis tirst collected in the chambers t5 and 7. 'lhe impurities andparticles of metal which are mixed with the oil by the wearing away otthe bearing cups, accumulate ou the bottom ol the chamber 7 and may bedrawn ott through the plug 30 which t'or this object is provided with aperforation 3l. The clean elarilied oil flows through the apertures l'linto the chamber 8 which is tightly closed opposite the journal 13, andis trom here conveyed afresh to the journal. lThe plug 32 which is alsoprovided with a perforation serves For removing the oil t'rom thechamber S when the axle box is cleaned.

The object of the modification shown in the second torni otconstruction, is to en ablel the purifying ol the oitto he more lll lill
